OXIDIZED CARBON BLACKS AND APPLICATIONS FOR LEAD ACID BATTERIES

Disclosed herein are oxidized carbon blacks, which can be incorporated into electrode compositions for lead acid batteries. In some embodiments, the oxidized carbon blacks have a BET surface area ranging from 650 to 2100 m2/g; an oil absorption number (OAN) ranging from 35 to 500 mL/100g; and a vola...

More Information
Summary:Disclosed herein are oxidized carbon blacks, which can be incorporated into electrode compositions for lead acid batteries. In some embodiments, the oxidized carbon blacks have a BET surface area ranging from 650 to 2100 m2/g; an oil absorption number (OAN) ranging from 35 to 500 mL/100g; and a volatile content of at least 5.5 wt.% relative to the total weight of the oxidized carbon black, as determined by weight loss at 950°C. La présente invention concerne des noirs de carbone oxydés, qui peuvent être incorporés dans des compositions d'électrode pour des batteries plomb-acide. Selon certains modes de réalisation, les noirs de carbone oxydés présentent une surface BET variant de 650 à 2 100 m2/g ; un indice d'absorption d'huile (OAN pour Oil Absorption Number) variant de 35 à 500 ml/100 g ; et un contenu volatil d'au moins 5,5 % en poids par rapport au poids total du noir de carbone oxydé, tel que déterminé par la perte de poids à 950°C.
